The Supply Chain Integrity, Transparency, and Trust (SCITT) architecture permits distinct Issuers to agree on the same CBOR Web Token (CWT) Subject Claim (sub) value for a common Subject. This document specifies one profile by which those Issuers can independently compute that common value from the same application- defined Subject semantics without relying on a shared assigning authority. A surrounding application maps its Subject description to an admitted structured Value. This profile defines an exact deterministic binding encoding, SHA-256 derivation, a text representation, and verification requirements for deriving sub from that Value. Optional JSON and Concise Binary Object Representation (CBOR) forms are provided for exchanging an admitted Value; they are not SCITT Statement payload formats. The SCITT Statement payload, signature, Registration, Receipt, Transparency Service state, and Issuer identity are not implicit inputs to Subject derivation.
